INDIGATIN G ATTACHMENT FOR COMPUTING SCALES.

Specification of Letters Patent.

Patented Jan. 10, 1922.

Original application filed January 27, 1913, Serial No. 744,443. Dividedand this application filed Jannary 12, 1918.

To all w ham it may concern:

Be it known that I, CLARENCE H. HAPGOOD, a citizen of the United States,residing at Toledo, in the county of Lucas and State of Ohio, haveinvented certain new and useful Improvements in Indicating Attachmentsfor ComputingScales, of which the following is a specification.

This invention relates to indicating attachments for computing scales,and more particularly comprises a device ,for conveniently indicatingthe prices of various commodities in proximity to the computing chart.

Often it is found that a salesman or clerk reads-the wrong indication onthe computing chart because he is not certain of the price per pound ofthe commodity being weighed, and the result in the course of a day orweek may mean a considerable loss to the proprietor or customers. Withthe use of my invention this difficulty can be overcome, as in case thesalesman is forgetful or uninformed as to the prices of variouscommodities, and especially in the case of commodities whose pricesfluctuate from day to day, the indicators showing the prices of thevarious commodities are suspended in their proper positions adjacent theseveral price columns of the computing chart, and thus form an efficientmeans of refreshing the memory of the salesman.

The invention herein claimed was first disclosed in my application forweighing scales, Ser. No. 744,443, filed January 27, 1913, now PatentNo. 1,253,239, issued January 15, 1918, and this case is filed as adivision thereof.

Reference is to be had to the accompanying drawings illustrating apreferred embodiment of my invention and wherein similar referencenumerals designate similar parts throughout the several views. 1

In the drawings Figure 1 is aside elevation. of a computing scaleequipped with my improvements;

Figure 2 is a front elevation of the upper portion thereof;

Figure 3 is an enlarged detail view of the indicator tags;

Figure 4 is an edge view thereof; and

Figure 5 is a detail sectional view showing one of the indicator slidesin position upon the slide bar.

Serial No. 211,515.

Referring more particularly to the drawings, the base 5 supports thehousing 6 upon which rests the casing 7 containing the cylinderindicating mechanism 8 upon the periphery of which is mounted a chartbearing weight and value graduations in the usual manner of computingscales. The cylinder 8 is secured upon a shaft 9 which also carries apinion 10 meshing with a rack 11 secured at its lower extremity to thescale beam 12. The scale beam is preferably a lever of the second order,and is supported adjacent its forward extremity upon standards 13carried by the base 5, the platform 14 resting upon the scale beamintermediate its fulcrum and its point of connection with theweight-offsetting and indicating mechanisms. The weight-offsettingmechanism may consist of a pendulum or any other desired form ofcounterbalance mechanism, so arranged that when a commodity is placedupon the scale platform the counterbalance member will be swung to aposition in which it will offset the weight of the commodity and therack actuating the indicating mechanism will be moved to a position inwhich it will indicate this weight. A dash pot 15 or other suitableclamping device is preferably employed to prevent undue oscillation ofthe scale beam and connected members.

As herein shown, the cylindrical chart 8 is arranged with parallel rowsof priceindicating numerals, each of the rows inclicating the values ofvarious weights of commodities at a particular price per pound. Theprice per pound shown by each column is marked upon a member carried bythe chart casing immediately below the horizontal. sight opening on thesalesmans side. To conveniently indicate which of these price columnsare to be used in determining the value of the commodity then beingweighed, I have arranged means whereby a plurality ofcommodity-indicating tags may be suspended adjacent any or all of theprice columns. Immediately in front of and below this elongated sightopening I mount the horizontal rod 16 supported in ears 17 projectingfrom the casing and upon which rod a plurality of indicating slides 18are free to be moved longitudinally of the rod to any desired position.Each of the indicator slides 18 preferably comprises arms arranged toconveniently fit over the bar 16 and an upwardly-projecting ear fillupon which is mounted a pointerQO which may be brought into registerwith any of the price indications upon the lower edge of the sightopening. When the desired position on the horizontal bar is reached theslide 18 is firmly clamped by means of a set screw 21 (see Figure 5). ofthe arms of the slide 18 is formed with an eye 22 for the reception ofthe 11001123 of a tag 24 bearing the name of any commodity which isdesigned to be sold with the aid of the scale. Each of the tags (whichare best shown in Figure 3) is provided at its lower edge with an eye 25into which may be inserted the hook of another tag so that any desirednumber of tags bearing the names of different commodities may-besuspended from a single indicator slide. Cbvicusly any number of theseslides may be used up to the number of columns upon the chart and asmany commodityindicating tags suspended from each slide as is desired. 7

"While it will-be apparent that the illustrated embodiment of myinvention herein disclosed is well calculated to adequately fulfill theobjects primarily stated, it is to be understood that my invention issusceptible to variation, modification and change without departing fromthe spirit and scope of the invention as set forth in the 'subjoinedclaims. I 7 Having described my invention, I claim:
